Royal jelly is a honey bee secretion that is used in the nutrition of the larvae. It is secreted from the hypopharyngeal glands in the heads of young workers and used (among other substances) to feed the larvae in the colony.[1] Additionally, if a queen is desired, a chosen larva will receive large quantities of royal jelly as its only food source for the first four days of its growth. This rapid, early feeding triggers the development of queen morphology, including the fully developed ovaries needed to lay eggs. All larvae in a colony are fed royal jelly, but adult bees do not consume it at all
